CROWN PCC160 Details top

 

Crown's PCC Series Phase Coherent Cardioid microphones are unidirectional boundary microphones that offer exceptional acoustic performance in handsome, low-profile enclosures.

 

The PCC-160 is the industry-standard stage floor microphone, while the other models provide an elegant solution for discrete multi-mic applications such as lecterns and boardroom tables as well as altar, teleconferencing and distance-learning applications.

 

Each PCC Series microphone employs Crown's Phase Coherent Cardioid boundary microphone technology to provide impressive gain before feedback and directional pickup without sacrificing tonal quality. This results in microphones with a wide, smooth frequency response, free of phase interference from surface sound reflections. And the microphone's sensitivity is boosted 6 dB by the surface mounting.

 

Designed to withstand the rigors of the stage, the PCC-160 microphone has been finely crafted using the very best materials possible while maintaining affordability. Its low profile enables it to be placed inconspicuously on the stage floor, on a lectern, or any other appropriate surface.

 

The Crown® PCC®-160 (Phase Coherent Cardioid®) is a surface-mounted halfsupercardioid microphone intended for professional applications on stage fl oors, lecterns, conference tables, and news desks—wherever improved gain-before-feedback and articulation are important.

 

Similar to the Pressure Zone Microphone® (PZM®), the PCC is designed to be used on a relatively large boundary surface. Unlike the PZM, the Phase Coherent Cardioid uses a subminiature supercardioid mic capsule. Its directional polar pattern improves gain-before-feedback, reduces unwanted room noise and rejects sounds from the rear. Surface-mounting creates a “half-supercardioid” polar pattern and increases directivity 3 dB. Since the microphone capsule is placed on a boundary, direct and refl ected sounds arrive at the diaphragm in-phase. This coherent addition of direct and refl ected waves increases sensitivity 6 dB and prevents phase cancellations. The mic capsule is small enough to ensure phase coherency up to the highest frequencies in the audible spectrum, resulting in a wide, smooth frequency response free of phase interference. Clarity and reach are also enhanced. Self-contained electronics eliminate the need for an in-line preamp box.

 

The PCC-160 can be phantom powered directly from the console or other remote power source providing 12 to 48 volts. If battery power is required, a battery supply unit can be inserted anywhere in the mic line right up to the console or mixer. A “bass tilt” switch allows the user to tailor the low-end response for particular applications.

 

Thanks to its low profi le and black fi nish, the microphone becomes almost invisible in use. A side-mounted connector complements the form factor of the PCC-160, allowing the unit to be placed effectively at the stage edge, at the top of a lectern or in other tight spots. If desired, the cable can be hard-wired for bottom entry. The PCC-160W is fi nished in off-white to blend with church altars and other surroundings where lighter color is appropriate. The heavy-gauge, all steel body protects the unit from accidental abuse. Permanent mounting is enabled by screw holes in the base. Engineering attention-to-detail has assured years of troublefree use from this reliable microphone. Capable of withstanding up to 120 dB SPL without distorting, the PCC-160 will never overload in practical use. Its electret condenser capsule provides a wide, smooth frequency response from 50 Hz to 18 kHz. RFI suppression is included. Self-noise is low, and sensitivity is very high to override mixer noise in distant-miking applications. Output impedance is 150 ohms, balanced.
